摘要： A ball screw apparatus of a screw shaft circulating-type includes a nut having a first groove formed in an inner peripheral surface thereof, a screw shaft having a second groove formed in an outer peripheral surface thereof, and a plurality of rolling elements provided between the first and second grooves. A circulating groove is formed in the screw shaft so as to interconnect opposite ends in a spiral direction of the second groove of the screw shaft to form a closed-loop ball endless circulating passageway. Processing relief portions for preventing a processing tool of a rotary drive-type from interfering with the circulating groove when processing the second groove of the screw shaft by the processing tool are provided respectively at the opposite end portions in the spiral direction of the second groove of the screw shaft.

摘要： The outside diameter φ of a land portion 1c is set to be larger than a BCD. Thus, when a ball 3 goes into a deep portion (a portion close to an axis line O of a screw shaft 1), the land portion 1c of the screw shaft 1 guides the ball. Consequently, the circulation of the ball 3 can smoothly be performed.

摘要： A ball screw device comprises a screw shaft, a nut externally mounted on the screw shaft, and a multiplicity of balls interposed between thread grooves of the screw shaft and the nut. The screw shaft has a ball circulation groove for coupling downstream and upstream sides of the thread groove so that the balls are returned from the downstream side to the upstream side and thereby circulated in the thread groove of the screw shaft. The ball circulation groove has such a curved shape as to sink radially inward in an intermediate region in a rolling direction of the balls and has a curved shape protruding radially outward in both end regions, and is configured in the manner that the centrodes of the balls rolling in the both end regions and the balls rolling in the thread groove of the screw shaft satisfy predetermined conditions with respect to circulation of the balls.
